Retail-focused REIT, Liberty Two Degrees (L2D), has introduced three solar trees to its Eastgate Shopping Centre rooftop Piazza.
Serving to provide a source of renewable solar energy to the shopping centre and to increase public awareness of alternative and responsible energy sources, the three solar trees also form part of the company’s aim to activate rooftop spaces enabling customers to experience the mall setting differently while creating good, smart, and interactive spaces for shoppers to interact.
The solar trees are self-reliant, harnessing energy from the sun to illuminate at night. With a bespoke installation of lights, the trees also contribute to feature lighting in the Piazza, while operating off the grid and come ‘alive’ in the evenings on their own accord for approximately 5 to 6 hours.
“We aim to accelerate our positive impact on the natural environment and remain bold in driving our net zero commitments. The solar trees at Eastgate are an exciting initiative as we aim to implement renewable energy projects throughout our portfolio, while creating sustained value for our stakeholders. This initiative also aims to inspire customers to adopt sustainability practices in their everyday lives for the benefit of the natural environment” comments Jonathan Sinden, Chief Operations Officer at L2D.
“The solar trees form part of a wider Piazza project which includes a journey through an artistic interpretation of sustainability, community and nature for the benefit of future generations. The centre is able to present patrons with a renewed ambiance, and overall experience when dining out, or simply strolling through the Piazza”.
This initiative is in partnership with Architects Batley Partners, who took on the function of conceptualising a vision that would be befitting of the physical space, while matching the overall ethos of the centre with the goal of uplifting the atmosphere of the Piazza for shoppers.
The solar tree concept at the Piazza, inspired by a visit to Baine’ Baobabs in the Botswana Nxai Pan National Park, doubles as public art and further aims to bring new energy to the area, enabling photo opportunities and a sense of community and connectedness between visitors.
The aesthetics of the solar trees was dictated by the scale of the trees and their relationship to the shopping centre. Three is the smallest nuclear family unit in nature and with this, an ensemble comprising of a large ‘father’ tree which towers at 13.5 meters in height and 14 meters in diameter, a slightly smaller ‘mother’ tree, and the smallest being a ‘child’ tree, was conceptualised. This concept speaks to Eastgate’s philosophy of creating family-focused activities and forming relatable, community driven and memorable experiences.
The trees consist of tubular hollow steel sections that have a twenty-year lifespan requiring minor maintenance. The hollow steel sections mostly resemble tree ‘trunks’ and ‘branches’ and are extremely flexible, allowing for the necessary bendability, and convenient transporting and installation. The solar panels are set to operate for ten years and are easily replaced. The solar trees are covered in a stainless-steel net called Jakob Webnet procured from Switzerland, and within this net, infills were placed to create an architectural effect. Several solar photovoltaic panels mounted on top of each spiral, can provide light.
Efficiently generating energy since October 2020, the design, manufacturing and installation of the solar trees saw over 200 people contributing to the successful completion of this project. The contractor responsible for bringing to life and constructing the solar trees was Anchor ENGinuity.
“Anchor ENGinuity is exceptionally proud of this project. Having had many years of experience in the specialised steel field, the Eastgate Solar Tree project is one of the most Iconic steel structures in South Africa. Integrating the steel component with electrical, solar and stainless-steel cladding, really creates a very special and unique world class structure,” says Andrew Kirkland from Anchor ENGinuity.
“The state-of-the-art solar trees further enhance the Piazza’s offering to patrons and tenants alike, creating a sculptural, functional and sustainable environment, while entrenching our commitment to our patrons by providing them with iconic shopping experiences,” Sinden concludes.
